Piping For Water Units; Piping For Tankless Heater; Installing Burner; Oil Supply Piping - Slant/Fin Intrepid TR Series Installation And Operating Instructions Manual

TR Series
C. HOT WATER RADIATION VENTING Manual air vents should be
installed at the top of all "drops"(where piping goes downward).
Air must be vented or purged from all zone lines to permit proper
system heating.
D. PUMP LOCATION Locating low head pump(s) on return to boil
er is only acceptable in residences of one or two stories. (See
figure 6) The pump location shown in figure 7 is required in large,
multi story building installations, especially when high head
pumps are used and is also recommended for all applications.
E. A conventional compression tank may be connected to the 19
mm ( / ") tapping as shown in figure 7.

IMPORTANT: Hot water heating systems containing high water volume,
such as would occur with cast iron radiation, require special care with
air elimination. The circulator pump should be located on the boiler
supply pipe and the expansion tank and air scoop should be located
near the pump suction. (See Figure 6, Alternate Pump Location.)
PIPING TANKLESS HEATER (if used)
I. Heater capacities are listed on Page 2.
II. Pipe the built in tankless heater using the inlet and outlet tappings
indicated on the heater (figure 8).
A. Tempering valve (illustrated, but not furnished) is suggested to
provide more volume of temperate water to kitchen and bath.
B. High temperature water, for dishwasher and laundry, may be
piped direct.
C. A flow control valve should be used to control the rate of flow of
water through the coil, otherwise the heating capacity of the coil
will be exceeded. To insure sufficient hot water, the flow rate
through the coil should be limited to a maximum shown for inter
mittent draw in the ratings table on page 2.
RADIANT FLOOR, LOW WATER TEMPERATURE AND LARGE
WATER VOLUME SYSTEMS
A boiler by-pass loop, three way valve arrangement, primary secondary
pumping (with a boiler loop) or other acceptable method, must be
used to provide a minimum 130˚ return water temperature to the boiler.
This will prevent condensation on the cast-iron sections that can result
in poor combustion and damage to the boiler.
INSTALLING THE BURNER
See Burner Data, pages 12 to 14, and Burner Manual supplied with
burner. If burner is not mounted as received, mount to boiler, placing
flange over mounting studs. Use gasket between flange and boiler.
Distance between flange and nose of burner (insertion depth) must be
as indicated on page 14, (fig. 14).
CAUTION: DO NOT USE GASOLINE, CRANKASE DRAININGS
OR ANY OIL CONTAINING GASOLINE.

OIL SUPPLY PIPING

Install the oil tank or tanks and piping from tank to burner. Follow local
codes and practices, CSA B139 and the instruction sheet attached to
the oil burner pump. A one pipe system should be used for gravity fed
fuel systems and for lift systems, where the total lift is less than 2.5 m (8
feet). Where the total lift is greater than 2.5 m (8 feet), a two pipe system
must be used. In some instances, local codes may require a two pipe
system for below grade fuel oil tanks. Be sure to set up the fuel oil
pump for the piping system used; follow the instructions attached to the
pump. Be sure to include a good quality, low pressure drop fuel oil filter
in the supply line from the tank. This is necessary, especially at low fuel
oil flow rates (small nozzle sizes), to prevent nozzle plugging. See
Slant/Fin publication on one pipe and two pipe fuel oil systems.

WIRING THE BOILER

A. The wiring diagrams for the burner and boiler are enclosed
separately.
B. 24 volt control wiring should be approved Safety Circuit wire,
protected as needed.
C. Power supply wiring to the burner must be 14 gauge or heavier, as
required, and should have a properly fused disconnect switch. 120
volt wiring to pumps and safety controls must also be 14 gauge or
heavier. Wire must be enclosed in approved conduit.
D. All wiring must be installed in compliance with the National Electric
Code, or any local or insurance codes having jurisdiction.
E. Wiring to the boiler must come through an emergency power isola
tion switch with a clearly marked red switch plate. This switch should
be located so that it is apparent to the homeowner when entering
the basement or boiler room. The homeowner should be made
familiar with operating the switch (toggle) to provide or stop power to
the boiler
